Nate says

Hi,

May I know the answer of question 9?

I think

1.depreciation of maintenance equipment – Is indirect cost

2. The overtime premium incurred at the specific request of a customer

– direct cost

3. The hire of a tool for a specific job – indirect cost

Thank you

John Moffat says

If you look at the contents page of the course notes, you will see that at the end of the notes are the answers to all of the examples, and to all of the test questions!!

The answer is A.

(The hire of the tool is a direct cost because it is for a specific job)

Nate says

Thanks so much sir !

But I am still confused about the third one. I think the hire of a tool is the same as buying a new machine.

Can we allocate the cost of hiring tools to certain units?

John Moffat says

Hiring is only like renting and it is being used for a specific job – so it can be allocated to that one job (rather than it being spread over all the work).

kaavya says

I don’t get answer for the question below.Would you please help me to solve it?

An organisation operates a piecework system of remuneration, but also guarantees its employees 80% of a

time-based rate of pay which is based on $20 per hour for an eight hour working day. Three minutes is the

standard time allowed per unit of output. Piecework is paid at the rate of $18 per standard hour.

If an employee produces 200 units in eight hours on a particular day, what is the employee’s gross pay

for that day?

A $128

B $144

C $160

D $180

John Moffat says

Because the standard time is 3 minutes per unit, the total standard time for 200 units is 200 x 3 / 60 = 100 hours. They are paid 18 per standard hour, which gives a total of 100 x $18 = $180.

The guaranteed minimum is 8 hours x $20 =

$160, but this is lower than $180 so the pay is $180.

Hope that all makes sense

bentzion says

By the way, 200 X 3/60 comes to 10, not 100 (and 10 x 18 = 180)

Anyhow, if it’s an 8 hr day, how can he be paid for working 10 hrs?

thanks?

John Moffat says

OK – sorry, it was a typing mistake (but the answer is the same).

The reason he is paid for 10 hours is because he is being paid for piecework – he is being paid according to how many units he manages to produce. He does not work for 10 hours, but because he produces as many units as he does, the time allowed (the standard time) is 10 hours and so this is what they will pay him for.

It is a very sensible way of paying workers – to tell them that the faster they work (and therefore the more they produce) then the more they will be paid.

kumara says

i did it another way which i think is less complicated and less time consuming as well.

i’ve been looking for the variable cost per unit= {(170000-5000)-13000}/22000-160000=$5

TC= 135,000

VC= (80,000) =(16000*$5)

FC= 55,000

@20000 units= FC+SF+VC

55,000+ 5,000+(20,000*5) =$160,000 Ans

we avoid that part of 16000units and 4000unit and with that we need to add the SF its confusing rather work it as a whole. its my point of view but the lecture is very nice. thanks

Jide says

Sorry please can u help confirm, is the answer option B or D?

Thanks

John Moffat says

The answer to which question?

Jide says

Sorry, answer to question 5 on the cost classification part b test questions. It is B, right?

John Moffat says

Yes – B is the correct answer.

(Both lines must go through the origin (0) because the lower price applies to all units already purchased)

Dipty says

Hi. I can’t understand the explanations for question one. Why is the extra 5000 deducted from the difference in cost? Is the difference in cost always a fixed cost? When it says exceeds 17500 units, is it in the total or the highest activity level only?

John Moffat says

As I explained in my answer to your question yesterday, the difference is usually due to the extra variable cost of the extra units – the total fixed costs normally stay fixed (by definition).

However, in this question there is a stepped fixed cost – the fixed cost increases when the activity is more than 17,500 units.

Since the higher of the two activity levels (22000) is higher than 17500, the fixed costs must be higher than the fixed costs at the lower level (16000).

So….since the step up is $5000, then $5000 of the difference is due to the higher fixed costs. The rest of the difference is, as normal, the extra variable cost of the extra units.

Dipty says

hello! I cant understand the high low method! Is there any in depth but basic explanation regarding it? or may be an easier example? Thanks.

John Moffat says

Just suppose that you make 10,000 units and the variable cost is $5 per unit and the fixed cost is $10,000.

Then the total cost is (10000 x $5) + $10,000 = $60,000.

Suppose next month you make 15,000 units. Why should the total cost change? The fixed cost will stay the same, and so the only thing that will change will be the variable cost – an extra $5 for each unit.

So the total cost would not be (15,000 x $5) + $10,000 = $85,000

All we are doing with high/low is the same thing backwards.

The total cost went up by $25,000. The number of units went up by 5,000. Since the only reason for the increase is due to more variable costs, it must mean that $25,000 is the extra variable cost for the extra 5,000 units. So the variable cost per unit is $25,000/5,000 = $5 per unit.

heng says

Hi John,

From the course note in chapter 4, page 17- there got mentioned about the Responsibility centres:

a) cost centres

b) profit centres

c) revenue centres

d) investment centres

Why do we need to know about these responsibility centres?

Thank you.

John Moffat says

Because it affects the way that we measure the performance of the centre and of the managers.

(If you want me to answer your question then please in future ask in the Ask the ACCA Tutor Forum for Paper F2)

Mahrukh says

Kindly help with this question

A company has obtained the following results from four years of trading:

Year Volume of Total cost

production $

2009 10,000 220,000

2010 20,000 340.000

2011 40,000 430,000

2012 18,000 320,000

When production volumes are above 30,000 units fixed costs rise by 50%.

What will predicted costs be at output of (a) 25,000 units (b) 35,000 units?

I’ve calculated a variable cost of 4 p.u. Fixed cost of 180000 at 25000 units & 270000 at 35000 units. Total cost = 410000 at 35000 units and 280000 at 25000 units. The problem is that if I multiply V.C. of 4 p.u. with 18000 units and add F.C. of 180000 it doesn’t equals the total cost given in the question at 18000 units. Same problem is with 20000 units.

Please help!

John Moffat says

If you want an answer from a tutor, then in future please ask in the Ask the ACCA Tutor F2 Forum – not as a comment under the lecture.

However, I do not know how you managed to calculate a variable cost of $4 per unit.

First of all use 2009, 2010, and 2012 (because they are all below the 30,000 units).

For high/low, you take the years with the highest and lowest levels of activity, which are 2009 and 2010. This gives a variable cost of (340,000 – 220,000) / (20,000 – 10,000) = $12 per unit.

Using this $12, you can calculate the fixed cost as being $100,000 per year (rising to $150,000 for levels of activity about 30,000)

You can then use this to get a total cost for both 25,000 units and for 35,000 units.

Andreea says

Good afternoon!

I have a question regarding the variable and fixed costs per unit and I was hoping you could clear it out for me.

I looked over a table in my text book, where it says that the variable cost per unit is constant when the volume of production increases, and the fixed cost per unit decreases while production increases. I am really confused about this. Shouldn’t the fixed costs be constant regardless of output and variable costs vary accordingly to the volume of production? Thank you!

John Moffat says

I think maybe you are reading it too fast

The book is correct (and says the same as my lecture).

Variable costs are fixed per unit – it is the total variable cost that changes with the number of units.

Fixed costs are fixed in total, but the fixed cost per unit will fall with more units being produced.

(If the fixed cost is $10000 and you produce 10000 units, then each unit costs $1. If you produce 20000 units, then the total cost stays at $10000 but the cost per unit is then $0.50 )

Andreea says

You are right-I didn’t think it through properly. I am clear now :D. Thank you again very much!

John Moffat says

You are welcome

Andreea says

Hello everyone! Can someone please tell me what does: ” overtime is paid at a rate of time and a quarter” mean? For example: workers are paid $10 per hour and this week they have worked a total of 20 hours overtime: 12 hours on specific orders and 8 hours on general overtime. How do I compute the specific overtime, keeping in mind that ” overtime is paid at a rate of time and a quarter”? Thank you!

John Moffat says

It means that for every hour of overtime they are paid for 1.25 hours.

So if they work 12 hours overtime they will be paid for 12 x 1.25 = 15 hours at $10 =

$ 150

(Alternatively you can get the same answer by paying the overtime hours at 1.25 x the normal rate. So 1.25 x $10 =

$12.50.

12 hours at $12.50 an hour = $150 )

Andreea says

Thank you so much!!! It’s clear now:)

Emily says

These lectures are so helpful! Thanks so much, they’re very clear and easy to understand!

ibrahim says

most of the topics in f2 are missing in these lectures.plzzzzzzzzzzz included that topics

John Moffat says

Rubbish! Most of the topics in F2 are included in the lectures – and all the more important topics are certainly covered.

Those that are not in the lectures are covered in the Course Notes for you to read yourself.

There will not be more lectures.

makunka says

For this examination we will assume that total variable costs vary linearly with the level of

production (or that the variable cost per unit remains constant). In practice this may not be the

case, but we will not consider the effect of this until later examinations.I NEED HELP :MEANING.:)
